Hello everyone!

Hope You are all doing great. I need to know how to remove a steel drill bit that broke off in a pearl? The pearl was undrilled (it is now) and I used a 0.5mm drill bit which broke inside the pearl (so no part of it sticking out). I then drilled the pearl on the opposite side and luckily managed to get through to the drill bit from that side. Both wholes are much bigger than the initial 0.5. I tried hammering it out to no avail.. Searched for solution online and someone suggested covering the pearl in beeswax and dipping leaving it in room temp. sparex solution. The only problem is - Sparex is not available in UK (and rather expensive to get it from US). I also tried drilling the steel bit out with tungsten drill bit but that broke as well (got that one out ) So my question is - would anyone know of any solution to getting the goddamn drill bit out? I tried finding another pearl, again to no avail (there were similar but at eye watering prices)...

Thank you beforehand for any help!!
